Page 12: General Description
Instruction book General description Introduction General QED air dryers remove moisture from the compressed air by cooling the air to near freezing point. This causes the water to condense. The condensate is automatically drained. The dried air is warmed up before leaving the dryer. - Page 13 Instruction book QED-250 up to QED-600 - side view The front panel and the side panel can be removed for service operations.
